Note this is an old v5.10 kernel on ARM64. No indication of whether
the problem occurs on a recent kernel.
We had an earlier issue with i210 when the disabled ROM BAR
overlapped BAR 3 [1] and the watchdog triggered:
BAR 0: 0x40000000 (32-bit, non-prefetchable) [size=1M]
BAR 3: 0x40200000 (32-bit, non-prefetchable) [size=16K]
ROM: 0x40200000 (disabled) [size=1M]
...
NETDEV WATCHDOG: enP2p1s0 (igb): transmit queue 0 timed out
Hardware name: Kontron SMARC-sAL28 (Single PHY) on SMARC Eval 2.0 carrier (DT)
igb 0002:01:00.0 enP2p1s0: Reset adapter
But this case looks different because there is no ROM BAR at all.
From the dmesg attached at [2]:
pci 0000:01:00.0: BAR 0: assigned [mem 0x18100000-0x1817ffff]
pci 0000:01:00.0: BAR 3: assigned [mem 0x18180000-0x18183fff]
pci 0000:01:00.0: BAR 2: assigned [io 0x1000-0x101f]
...
igb 0000:01:00.0: Detected Tx Unit Hang
NETDEV WATCHDOG: eth1 (igb): transmit queue 1 timed out
I'm assuming this is a driver issue, not a PCI core issue. But please
ping me if you think otherwise.
